Application filed July 5, 1919.

To all whom it may concern.

Be it known that l, VVILLIAM WALL-ion HnssoN, a subject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in il obacco Pipes, described in the following specification and illustrated in the accon'ipanying drawings, that form part of the same.

The principal objects of this invention are to eliminate the undesirable conditions following the continued use 01 a pipe and to enable the removal oi parts that may become saturated or burned and to iii ise a pipe in which the separable parts will be free from leakage and other conditions permitting the accumulation of nicotine.

The principal feature of the invention consists in the novel construction and arrangement of parts whereby a removable bowl lining is securely held in an outer bowl and directly connected with the mouth piece in a continuous sealed pi age.

The drawing is a vertical sectional view through the pipe bowl and stem.

In the use of a tobacco pipe, it is extremely desirable that the pipe should not be used when the bowl becomes saturated with nicotine as it results in the noxious fluids being carried to the mouth and it is the purose 01 this invention to eliminate this con dition by providing a structure of pipe in which the lining may be replaced.

It has been. previously proposed to provide removable linings but as far as I am aware the structures produced have not been suita- Specification of Letters Patent.

ble in that there has not been maintained a definite sealed connection between the bowl lining and the mouth piece.

In the construction herein shown, the bowl is open at the bottom and the lining 24; Which may be of any suitable material. is inserted from the bottom so that the upper edge abuts the shoulder 25 at the top of the bowl and a cap 26 is threaded into the bottom against the lining. The lining is provided with a fa dial hole 27 which may be tapered or threaded as desired 'to receive the inner end of a tubular stem 2% which is threaded into the removable mouth piece which definitely connects the mouthpiece with the inner bowl or lining in a sealed passage and there will be no recess in which nicotine or undesirable elements may secrete.

When the bowl lining becomes saturated or burned to an undesirable degree, it is merely necessary to remove the mouth piece and inner stem and the cap and the lino; may then be withdrawn and replaced with a new one.

What I claim as my invention is A tobacco pipe, comprising, an outer bowl member iormed oi? two separable portions one of which has a shoulder, threaded tonether, a removable bowl lining of absorbent material adapted to lit sni'igly within the outer bowl and to be clamped between the shoulder portion and the other portion of the outer bowl, a mouth piece, and a tubular extension from said mouth piece entering the side wall of said lining at the bottom.
